- didn't know (to look for) that
.
Calibre always seems to start a *worker process* as child and it in turn starts a *console window host*, as in
So what could possibly stop calibre from starting another worker branch to do a conversion, open a file for viewing etc. Something to do with
Windows Process Security maybe.

steve2112 - did running in safe mode provide any insight? If it works then that would point to one of your start up tasks interfering.
In Sysinternals Process Explorer you can look at the Process Properties (right click menu) where there's a Security tab that shows Process Permissions, you might want to take a look in there for 'something' askew - sorry I've no idea what.
Task Manager's Properties/Security tab shows the File Permissions - this suggests MS doesn't know the difference between a file and a process, or a permission and a persimmon
